Metrel MI 2123, TEK 3660.  Megger Insulation Testers at least 10 insulation testers like the MIT300 MIT310 MIT310A - MIT320 - MIT330 MIT220 and MIT 230. Industrial models include the MIT 440 - MIT400 - MIT410 - MIT 420 - MIT430 - MIT40X. Telecoms insulation and continuity testers include the MIT 480 - MIT481 and MIT 485. A low resistance between phase and neutral conductors, or from live conductors to earth, will result in a leakage current. This current could cause deterioration of the insulation, as well as involving a waste of energy which would increase the running costs of the installation. Thus, the resistance between poles or to earth must never be less than half of one meg ohm
